I have only done the UV5 series but I believe it is the same procedure. If using chirp, install the drivers from Baofeng that were with the programming cable,. then install Chirp. Even if it doesn't show complete go ahead and open Chirp. After that, the updates for chirp will install OK.

Your question is not very specific. Do you have a programming cable? Can you access the internet on a laptop with a USB port for that cable? You CANNOT program radios from a phone or tablet. Get the programming cable, I got mine on Amazon. This is the software I like to use: https://chirp.danplanet.com/projects/chirp/wiki/Home
